Video Piper — Video API for developers: transcode, trim, stitch & redact

Everything video, nothing to babysit

The parts of video you'd rather not build yourself

Encoding farms, chunking, A/V sync, edits and privacy. We run the hard parts on autoscaling AWS infrastructure, so your app just calls an API.

Fast parallel encoding

Long videos split into frame-exact chunks and encode side by side, on GPUs for long files. Short ones finish in a single pass.

Trim, stitch & splice

Cut any range, join clips with hard cuts, crossfades or fades to black, and splice inserts — all frame-accurate.

Redaction

Blur or black out regions — rectangles or ovals, each on its own time window — and delete the unredacted original.

Screen + camera

Two recordings in, one picture-in-picture video out, with both audio tracks mixed and in sync.

Upload while recording

Stream parts as they're recorded while processing warms up. Recordings are ready about a minute after you stop.

720p to 4K

Pick the top quality per video; every lower level is made too. Videos are never upscaled.

Validation & dry runs

Every problem in a request comes back at once with its field path — before anything runs. Dry-run any request.

Keys per user

Issue an API key per customer or teammate, each with private videos and its own daily limit. Revoke in a minute.

Edits

A timeline, as JSON.

Cut a section out, stitch an intro and outro, or splice an insert into the middle. Send clips in order; we render the timeline and encode it like any upload.

Cuts land on exact frames; audio stays in sync across every join

Privacy

Hide what shouldn't be seen.

API keys on screen, a face in the corner, a customer's email. Mark regions as blur or solid black, even on things that move, and they're burned into every quality level, the download and the thumbnail.

Rectangles or ovals, each with its own start and end
Optionally delete the unredacted original after processing
Follows moving faces and objects: set a few keyframes and it glides between them

Recording

Ready a minute after you hit stop.

Record screen and camera in the browser and stream parts as they're made. Processing boots while you record, so there's no upload wait and no cold start at the end.

Screen and camera combined picture-in-picture, both mics mixed
Cancel anytime: parts, job and record are cleaned up

Developer experience

Designed by people who read error messages

Predictable REST, a complete OpenAPI spec and errors that tell you exactly what to fix.

Errors you can act on

Every problem at once, with its field path and a stable code.

400 { "error": "INVALID_REQUEST",
  "details": [ { "field": "edit.clips[0].end",
    "message": "80s is past the end of
    the video, which is 60.0s" } ] }

Dry runs

Validate any request against real video lengths without creating anything.

POST /v1/videos?dryRun=true
200 { "valid": true,
  "duration": "49.0s (0:49)" }

Uploads that don't fall over

Bytes go straight to storage in parallel 64 MiB parts. Retry a part, not the file.

FAQ

Questions developers ask

What video formats can I upload?

MP4, MOV, MKV, WebM and most other common formats, up to 20 GiB and 8 hours per file. Browser recordings (WebM) are fully supported.

How fast is processing?

Short videos are usually ready within a minute or two. Long videos are split into frame-accurate chunks and encoded in parallel, on GPUs for long files. With upload-while-recording, a recording is typically ready about a minute after you stop.

Can I trim, stitch or splice videos?

Yes. Trim any upload at no extra cost, or create an edit from clips of your finished videos with hard cuts, crossfades or fades through black. Cuts land on exact frames.

How do I hide sensitive information?

Send up to 20 redaction regions — blur or solid black, rectangle or oval, each for its own time window — and optionally delete the unredacted original after processing.

How is usage billed?

Plans include processing minutes, storage and delivery. Minutes are counted per output minute (at least one per video); 1440p counts double and 4K four times. Usage beyond your plan is billed per unit.

Can my end users upload from the browser?

Yes, without exposing your key: your backend creates the upload and hands the browser short-lived pre-signed part URLs. The docs walk through it.
